Consider Lundy Solar And Roofing if...
- ✓ Your project involves both roofing work and solar installation, where having one contractor handle both eliminates coordination issues and warranty confusion if problems arise.
- ✓ You're concerned about long-term reliability and want a contractor with a documented track record of supporting customers years after installation.
- ✓ You value detailed communication throughout the project and want a company consistently praised for explaining complex technical processes clearly.
- ✓ Your roof may have underlying issues like dry rot or structural concerns that require experienced assessment before solar panels are mounted.
Consider Sunvault if...
- ✓ You're getting multiple quotes purely for price comparison and Sunvault's pricing proves substantially lower after carefully evaluating what's included.
- ✓ You're working with a tight deadline related to net metering or incentive programs and Sunvault can commit to a faster timeline.
- ✓ You're comfortable investing extra time in project oversight and quality inspection during and after installation.
- ✓ Your roof is newer, structurally sound, and you're confident no roofing expertise is needed for the solar installation.
Questions to Ask Before Hiring
- → Ask Sunvault specifically about the workmanship concerns mentioned in reviews: what follow-up was required, how they've changed processes since, and what inspection checkpoints they now use.
- → Ask both companies for references from solar projects completed 3-5 years ago so you can verify long-term system performance and panel degradation.
- → Ask Sunvault whether they subcontract any roofing work needed for solar installation or handle it in-house, and who warranties roof penetrations.
- → Ask Lundy about their current solar installation volume and whether they maintain dedicated solar crews or cross-train roofing teams.
The Bottom Line
For most homeowners, Lundy Solar And Roofing is the clearer choice. Their 16 years of experience, consistent customer satisfaction, dual roofing-solar expertise, and documented long-term support provide substantially more confidence for a major investment that needs to perform for decades. The workmanship quality concerns in Sunvault's reviews are particularly troubling for solar installations where problems may not appear until months or years later. Sunvault could make sense only if their pricing is dramatically lower and you're prepared to invest significant time in quality oversight, but even then, the risk may outweigh savings. Get quotes from both, but unless Sunvault's price is exceptionally compelling and they can thoroughly address the workmanship concerns with verifiable process changes, Lundy's proven track record makes them the safer investment.

Frequently Asked Questions
Yes, significantly. Solar installations require assessing roof structural capacity, identifying hidden damage that could worsen under panel weight, properly flashing roof penetrations to prevent leaks, and troubleshooting electrical integration issues. A contractor with 16 years has encountered and solved problems that a 6-year contractor simply hasn't faced yet. Lundy's customer feedback about long-term support also suggests they'll be available if issues arise years down the line.
Yes. When reviews specifically mention quality concerns requiring follow-up evaluation, that's a red flag for a 20-25 year investment like solar panels. Poor installation can lead to roof leaks, electrical problems, voided warranties, or underperforming systems. While every contractor occasionally has issues, patterns of workmanship concerns suggest inconsistent quality control that puts your investment at risk.
For most homeowners, yes. If your roof needs any repair or reinforcement before solar installation, having one contractor handle both eliminates the warranty confusion that happens when roof leaks develop after solar installation. Solar-only companies often subcontract roofing work, creating finger-pointing situations. Lundy's customers specifically praise their combined roof and solar projects, suggesting smooth coordination between the two trades.
Only if the price difference is substantial and you're prepared for potential quality issues. Remember that fixing problems with solar installations is expensive and disruptive, often requiring panel removal to access roof issues. Lundy's customers describe their pricing as competitive and reasonable, so the gap may not be as large as expected. Get detailed quotes from both and evaluate what's actually included before deciding based on price alone.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
